. BEATING-EKGINE.

To all whom it may concern:

Be it 'known that we, JAMES T. MURPHY and EDWARD J. RANEY, residing at Chicago,

in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Beating-Engines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates-to improvements in beating engines.

The objects of our'invention are:

First: To provide means for continuously removing the formed stock from the en e, which will prevent strings, rags, etc., rom

' passing with the formed stock out of the en ine. And

becond: To provide means forremovingthe formed stock from beating engines, 'meluding means for separating strlngs and rags therefrom, of such a character that the strings and rags will not adhere to said means.

Other objects will appear as this description progresses, reference being had to t e accompanying drawings, in .which:

Figure 1 is a beating engine embodying our invention.

Fig. 2 is an enlarged fragmentary section View through a portion of the beating engine, showing our improved means for removing stock therefrom, the. said means being shown partially in elevation and partially in section. And

Fig. 3 is an end elevation of the construction shown in Fig. 2.

In the several views similar reference char-. acters refer to similar parts.

Beating engines are in use in which large rotary cylinders having holes formed in the periphery thereof are used for continuously removing the formed stock from the beating engine. When using beating engines of this, type for forming stock for various grades of paper from old papers and other similar material, diflicult'y. has been experienced by reasonof the fact "that these old papers con tain strings, rags, etc., which collect on the periphery of the cylinder which removes'the formed stock from the beating engi e and thus prevents the entry of the formed s'tock into the cylinder. Means'have been provided for scraping or otherwise removing these strings and rags from the surface of Specification of Letters Intent.

*Referring to Fig. 1, where we have conventionally illustrated an ordinary beatin engine equipped with our-invention, the re erence character 5 indicates the tank of the beating engine, which is divided by a partition 6 in a manner well known. The referay sultable means, as, for instance, the belt pulley 10. The construction thus far described is well known in this art, and forms no part of our invention, except as it enters into the combination recited in the appended I claims. Y

.Our novel means for removing the formed stock from the beating engine is in the form of a cylinder, indicated as a; whole by the reference character 11. This cylinder comprises two end members '12 and 13 respectively, spaced apart upon the shaft 14, which is rotatably mounted in suitable bearings 15, one of which is secured to the partition 6, and the other of which is secured to the wall Patented July 22, 1919.

of the tank 5. The periphery of the cylinder' is formed of a plurality of cylindrical rollers 16, which are rotatably mounted in the end members 12 and 13 by means of pins 17,, which find hearings in the annular segmental bearing blocks 18 that are secured to the peri heries of" the end members 12 by'means 0 suitable screws 19 (see Fig. 3). The inner sides of the bearing blocks 18 are provided with flanges 20 which extend over the adjacent, ends of the rollers to prevent the strings and rags from becoming Wound about the pins 17. a

r .The interior of the cylinder formed by the means just described is divided into a plurality of compartments by radially extending partitions 21, which are secured to the ends of the cylinders and extend radially from a point adjacent the rollers 16 to a point adjacent the shaft 14. The compartments formed by the partitions 21 are provided with plates 22 which form bottoms for these compartments when these compartthe end niember 12. Strips 21 are secured tents'through the Openings 23 formed in the end member 12, ad acent the center thereof. It will be noted from an inspection of Figs. 2 and 3 that, these plates are inclined from points adjacent the periphery of the end member 13 to points adjacent the center of to the outer ends of the partitions 21, and project in the direction of rotation of the cylinder. These strips 21' co-azct with the partitions 21 to form scoops for retaining the stock which enters the cylinder between the rollers 16 and carry it to a point above the center of the cylinder. The shaft 14 extends through a bell, into which the openings 23 discharge the stock. This bell discharges the stock and water contained therein into the trough 24 which leads to a stun chest or any 1 other suitable means for re-.

ceiving the stock.

Any suitable means may be used for rotating the cylinder 11, andin the accompanying drawmgs we have'illustrate id this .cylin-L der as being rotated vfi'ornltheshaft" 'igof the. beating engine. -To '-.do' .this w"e'mount a counter shaft 25 in suitablebearingssecured to one of the bearin blocks, 9. This is provided at one en witha pulley 26,-'which: means-of seen, 27. The pinion 28 is secured to the'other' end of the shaft 25, andmesheswithasuitff able gear 29, which is securedto. the shaft. 14. By this means the cylinder. 11 is- *r'o-i} tated in a direction opposite ,to the direction engine,.the said cylinder complrising a pair is driven from the shaft 7' by of rotation of the beater roll 8, or in other words, the portion of the c ylinder 11 which dips beneath the surface of the stock in the tank 5 moves in the same direction as the stock in this tank.

In operation, the formed stock passes between the rollers 16, which are spaced apart different distances, depending upon the character of the stock that is being formed, vand into the compartments formed by the radially extending partitions 21. As the wheel continues to rotate, this stock is carried upwardly by means of the scoops formed by the partitions 21, and the strips 21, until it reaches a position adjacent the top of the c linder, whereupon it slides down the inclined plates 22 by gravity and is discharged through the corresponding opening 23 in the end member 12, into the bell, and from thence into the trough 24. It will thus be seen that we have rovided very simple means for delivering t e stock from the beating engine to the trough 24.

We have found by experimentation that very satisfactory results are obtained in the way of preventing strings and rags from adboring to the periphery of the cylinder,

merely by the use of cylindrical members exwe do not wish to limit our invention to the use of member 16 rotatably mounted in the end members 12, even though more satisfactory results are obtained by this construction. We do not know the exact reason why the strin s do not accumulate upon cylinders of t 's construction, but it is probably because less frictional contact is ofiered to the strings and rags than with cylinders having continuous peripheral portions.

While we have described the rotating member of our invention as being a cylinder, we wish it to be clearly understood that our invention is not confined to the useof a cylinder which is circular in cross .section. While the cylinders can perhaps be more economically constructed in this manner, our invention would function satisfactorily if it had an octagonal or other cross section. Furthermore, the roller 16 need not be circular in cross section but may similarly be 7 made with. any number of sides.

While we have described the details of the preferred embodiment of our invention,our

*invention is not to be limited to these details,
